Answer:
6.022 x 10^23 particles
Explanation:
Chemists have chosen to count atoms and molecules using a unit called the mole (mol), from the Latin moles, meaning “pile” or “heap.”
One mole is 6.022 x 10^23 of the microscopic particles which make up the substance in question.
Hope this helped! :^)
Answer:
the answer is A
Explanation:
A is the answer because they never run out of it unlike nonrenewable resources.
A mass extinction is the rapid decrease in something. so anytime that graph goes down drastically would be a mass extinction
Answer:
You also know about the mass of that sample, if you know the moles
(First option)
Explanation:
Moles = Mass / Molar mass
Moles . Molar mass = Mass
For example, I have 4 moles of H₂O
Molar mass H₂O = 18 g/m
4 m . 18 g/m = 72 g
If I have 4 moles of H₂O, I also have 72 grams of water too.
